AWNING-OPERATING MECHANISM. A 1

.Application led November` 8, 1924. i Serial' No, 748,714. i

To all whom it may concern:

Be it known that I, ABRAHAM: SoNDAoK, a citizen of Russia, residing at Bronx, New York city, county of Bronx, and State `of NewYork, have .invented certain new and useful Improvements in Awning-Operating Mechanismspof which the following is a specification.

This invention relates to improvements in awning operating mechanisms1 and` has particular reference to a locking device therefor. An object of the invention is to provide an improved. mechanism wherein the operating parts thereof are released from a. normally locked condition by the insertion of an operating handle in the casing of the mechanism.

Another object is to provide a locking `device for the operating. mechanism which is actuated toa non-locking position by engagement therewithof an operating handle and which is restored to its locking position by the withdrawal of said handle.

lThe above and other objects will appear more clearly from the following detailed description,.whe`n .taken in connection with the accompanying drawings, which illustrate preferred embodiments'of the inventive idea.

In the drawings- Figure 1 is a vertical longitudinal section showing o ne form of the invention ywith the mechanism in its operative position;

Figure 2 is a similar view showing the mechanism in its inoperative position;

Figure 3 is a section on the line 3-3 of vFigure 1;

Figure Figure 2; f

Figure 5 is a view similar to Figure 2 4 showing va slightly ldifferent form of the invention;

.Figure 6 is a section on the line 6-6 of Figure 5; and

Figure 7 is a fragmentary elevation, partly. in section, of a slightly different' form of operatin handle. y l

. Referring more particularly to the form of the invention shown in Figures 1 to 4, the numeral 7 indicates a casing of substan* tially rectangular formation open at one end and providedA upon said end with a `lease 4 is a section on the `line 4.--4 of said partition also forms a support for the plate 8` designed to bei attachedl to a wall or other support. The open end of the casing is' closed by means of a closure `plate 9 countersunk in the inner face of the base plate 8j and detachably secured thereto byy means of screws 10 or othersuitable fasteners. l

In the top of the casing 7 lthe same lhas mounted therein abushing 11 in which the 60 squared V lower end of an operating shaft 12 is supported. rlhis shaft is of .the usual construction and is connected at its upper end through gears (not shown) or other well known mechanism utilized to raise and G5 lower the awning when the shaft 12 is rotated. The bushing 11, .which is rotatably mounted in the casing, is provided with an extension 13 projecting into the casing and having secured thereto the bevel gear 14. Theextension 13 has a bearing in a supporting plate or -partition 15, preferably cast integrally with the sides of the casing, and

bevel vgear 11i.

'I he front 16 of the casing is provided with an opening 17, in which the hub 18 of a bevel gear 19 is rotatably mounted. The inner end of the hub 18 is reduced and en! gaged in a supporting flange 20 depending 80 rom the supporting plate or partition 15, Said liange having an opening 21 therein for a purpose which will presently appear. The invention further provides means for locking the gearsV 1li and 19 against ro- 85 tation when the mechanism is not in use, which means is normally in an operative position and capableof being'moved to an inoperative position by the insertion of a portion of the operating handle 22 into the 90 casing. This means is preferably inthe form of a locking member, generally indicated by the numeral 23, supported within the casing 7, preferably adjacent the rear or closure plate 9. The locking member includes a locking vkextension 24 projecting through an opening 25 in the partition 15 and engageable between adjacent teeth of theV gear -14 to prevent rotation of `said gear when the locking member is in its-operative position. The lower extremityof the locking member 23 is lprovided with a lateral` projection 26 extending Jforwardly and formed upon its end with an enlarged portion 27 having an inclined surface at its forward end for a purpose which will presently appear. Depending from the projection 2G is a rod 2S, the lower end of which extends through the bottom of the casing 7. A coil spring 29 is interposed between the projection 26 and the bottoml of the casing to yieldably exert an upward pressure on the locking member to retain it in its locking position. The handle 22 is :termed with a lateral projection 30 of rectangular formation and capable of tting into the hub 18 of the gear l) and extending from said projection 30 is a pin 3l having a tapered head 32. When the projection 30 and pin 3l are inserted into the hub 1S the pin 3l extends through the opening 2l in the flange 2O and the head 82 engages the enlargement 27 of the locking member 23. As the pin 3l is forced inwardly, it will be obvious that the head 32 will force the locking member 23 downwardly against the tension of the spring 29 and thus disengage the locking extension 2l from the gear 14. The handle 22 may now be turned to impart a rotary movement to the shaft 12 to either raise or lower an awning.

Upon withdrawal of the handle the head 32 ot the pin 3l will be disengaged from the enlargement 27 of the projection 26 and the coil spring 29 will thereupon force the locking member upwardly until the extension 24; thereof is again engaged with the gear 14C.

In the form of the invention shown in Figures 5 and 6, the construction of the parts is identical with that previously described with the exception of the partition l5 and the locking member 23. Inl this instance, the partition l5, instead of having only one opening 25 therein, is provided with two openings 33 through which two locking extensions 34 project. These locking extensions are formed upon the ends of a transversely extending` plate 35' forming a part of the locking member 23. By the provision or' the two locking extensions 34, it will be apparent that said extensions when in engagement with the gear 14 will effectivelyv prevent rotation thereof in either direction. The operation of the mechanism is precisely the same as described in connection with the embodiment shownA in- Figure l.

In Figure 7, the handle 36 is provided with a lateral projection 37 similar to the projection 30 but made with an opening 38 therethrough in which the slidable pin 39 is mounted. This pin is provided at one end with a head 40 and at its other end with a knob 4l, which latter facilitates the sliding of the pinl in the projection 37. With this construction the locking member 23 may be operated simply by sliding the pin 39 back and forth without withdrawing thi` handle from its operative position.
